| 摘要 | An exemplary electronic light processing cell uses a photo sensor unit to provide an analog electrical output proportional to an amount of light impinging on the photo sensor. A noise source provides a noise output that is compared by a comparator, during a plurality of times during a frame of an image, with the analog electrical output to generate a binary digital output representative of each comparison. A digital counter counts the binary digital outputs during the frame and stores a count at the end of a frame where the value of the stored count is proportional the light impinging the photo sensor. The value of the stored count is adapted for use by an image processing unit to render an image. | ||||||
